Why Flexible Solar?

Flexible Modules vs. Polysilicon

Flexible Module



  • Can fit around curved structures
  • Can be integrated into materials

  • Not bendable
  • Requires racking to install

  • No retrofitting required
  • Can be used in applications such as consumer goods where weight is a concern

  • Roofs require reinforcement to support weight

  • Won’t break / Resistant to vandalism
  • No risk of microcracks to cells

  • Can shatter
  • Cells can develop microcracks
Bonded Directly to Surface

  • Lower installation costs
  • Resistant to theft
Requires Mounting Hardware

  • Drives up installation costs
  • Subject to theft
Thin —2mm – 3mm

  • Unobtrusive
  • Superior wind resistance
Thick —40mm – 50mm

  • Visible
  • Subject to wind uplift
Aesthetically Pleasing

  • Uniform “black-tie” appearance
  • Dark interconnect wires

  • Checkerboard appearance
  • Bulky paneling does not conform to the roof

  • 360W form factor for large TPO installations
  • More watts per KG
Not as powerful

  • Traditional 60-cell house module 260 – 290 watts
  • Utility sized 72-cell field module is only 290—310W

  • FLEX modules are lightweight – won’t injure people or property in high wind or earthquake
  • No cell degradation at high voltage
  • No grounding wires to corrode

Dangerous in environmental emergencies

  • Metal racks + box modules can damage people and property in an earthquake
  • Metal racks + box modules hazardous in the event of wind pull-off

How do we do it?

MiaSolé second-generation CIGS thin film, already in mass production, provides unparalleled thin-film cell efficiency at 16-17% and rising.  MiaSolé solar cells produce the world’s most lightweight UL certified solar module package.  Weighing in at a mere 0.7 lb / sqft, comprised of the most advanced PV laminate materials available and with a 25-year power warranty, they stand alone in a crowded field of heavy and brittle competitors.

MiaSolé begins with high-grade stainless steel foil and a physical vapor deposition processes to produce the most controlled, stable, and powerful flexible stainless steel CIGS cell in the world.  After the cell structure is deposited on the foil, special transparent conductive oxides are applied and then a very specialized plastic-cell interconnect mesh-wire system is laminated to the cell, which is in turn protected by special solar barrier plastics.  The transparent solar barrier is key to the longevity and high efficiency of the MiaSolé FLEX module series.  The special plastic backsheet has an internal aluminum film to prevent all water transmission or other contaminates from eroding the powerful stainless steel CIGS cells.

In the end our technology enables the world’s only real solution for lightweight, thin, certified, and highly powerful solar for many applications.
